In a
bowl, toss apples with raisins, maple syrup, lemon juice, vanilla, 1/2 teaspoon
of the cinnamon and nutmeg. Spread out apple mixture evenly in the bottom of a
buttered 9-inch deep-dish pie pan; set aside. Toss oats with the maple or brown
sugar, flour, remaining 1 teaspoon cinnamon and salt. Add butter and stir until
evenly moistened. Scatter oat mixture over apples all the way to the edge and
bake for 45 minutes, or until apples are tender and topping is golden brown.
Let rest for 20 to 30 minutes and then serve.
